Overview
The MPC509AU is a dual analog multiplexer switch integrated circuit manufactured by Texas Instruments. It features two independent 4-to-1 multiplexers configured for differential inputs, housed in a 16-pin SOIC package. The device operates on a dual supply voltage of ±15 V with a maximum operating voltage of 18 V. Key electrical parameters include a maximum on-resistance of 1.5 kOhms, a maximum power dissipation of 7.5 mW, and a maximum supply current of 1.5 mA. Switching performance is characterized by a maximum turn-on time of 500 ns and a maximum turn-off time of 500 ns. The component supports an industrial temperature range from -40°C to +85°C.
Feature Summary
- Supports differential input configurations for two independent channels
- Operates on dual power supplies within specified voltage limits
- Provides high isolation characteristics suitable for signal routing applications
Applications
- Data acquisition systems requiring differential signal selection
- Industrial process control instrumentation
- Test and measurement equipment signal paths
Procurement Notes
Verify the specific suffix 'AU' against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required SOIC-16 configuration. Confirm RoHS compliance status through the latest datasheet revision before procurement.
Selection Notes
Select this component when differential input multiplexing is required with ±15 V dual supplies. Compare on-resistance and switching speeds against alternative models if higher bandwidth or lower resistance is needed. Verify that the 1.5 kOhm on-resistance meets the application's signal integrity requirements.
Part Context
The MPC509AU belongs to the MPC509 series of analog multiplexer switches. This series includes variants with different channel counts and input types. The AU designation typically indicates a specific package and temperature rating within the broader product family.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Alternative parts may offer different pinouts or electrical specifications. Ensure any replacement maintains compatibility with the existing dual-supply design.
